Moshe and the Continual Lamp

Whereas regarding Moshe, which is the level of “returning to reveal the One Hashem in this world,” which reveals Hashem’s Oneness on the level of Yichuda Ila’ah, it is written: “it will be a continual lamp.”

Since it is a revelation of Hashem’s Oneness that is above the limitations of time, and before Hashem “darkness and light are the same” (Tehillim 139:12), since “He is always the same, and he makes everything else completely equal in comparison to Him.”

This explanation will be enough for one working to understand.
